Yes, a couple of years ago our agent showed us where our homeowner's policy had that provision. I have concerns about turning off city water, or using very little electricity due to that abandoned/vacant thing.
Coachmen still shows several floorplans on the Chevy 4500 chassis. Of course, Coachmen is owned by Forest River.
Our 2012 Coachmen is on the Chevy 4500. I love the chassis, but am not too happy with the build quality of the coach.
